Question

# The metal with the lowest density among the given options is:${\text{A}}{\text{. Mg}} \\ {\text{B}}{\text{. Li}} \\ {\text{C}}{\text{. Ag}} \\ {\text{D}}{\text{. Au}} \\$

Hint – To find out the metal with lowest density, we identify all the elements in the given choices and look into their respective densities.

Mg stands for Magnesium and its density is 1.738 $\dfrac{{\text{g}}}{{{\text{c}}{{\text{m}}^3}}}$
Li stands for Lithium and its density is 0.534 $\dfrac{{\text{g}}}{{{\text{c}}{{\text{m}}^3}}}$
Ag stands for Argentum also known as Silver and its density is 10.49 $\dfrac{{\text{g}}}{{{\text{c}}{{\text{m}}^3}}}$
Au stands for Aurum also known as Gold and its density is 19.30 $\dfrac{{\text{g}}}{{{\text{c}}{{\text{m}}^3}}}$
Density of an element is given by${\text{D = }}\dfrac{{{\text{Mass of the element}}}}{{{\text{Volume of the element}}}}$.
